"Divergent" fans: Have you ever wondered what your fear landscape would include if you were lucky(?) enough to join Dauntless? Well, so have cast members Shailene Woodley and Theo James, and their deepest fears are rather... briny.

Woodley and James joined Ellie Goulding Wednesday night for the premiere of her "Beating Heart" music video — a jam from the "Divergent" soundtrack — as well as a Q&A with "MTV First."

After dropping the video, the cast and Goulding got a little deep, delving into what scares them the most. Don't expect your standard, run-of-the-mill answers like "the dark" and "falling in love again" — these three stars have some pretty bizarro bugaboos.

Check out the video below to see what gets them shivering — then head to the comments and let us know: What populates your fear landscape?
